python实现带错误处理功能的远程文件读取方法

本文实例讲述了python实现带错误处理功能的远程文件读取方法。分享给大家供大家参考。具体如下:

import socket, sys, time
host = sys.argv[1]
textport = “80”
filename = sys.argv[3]
try:
s = socket.socket(socket.af_inet, socket.sock_stream)
port = int(textport)
s.connect((host, port))
fd = s.makefile(‘rw’, 0)
print “sleeping…”
time.sleep(10)
print “continuing.”
fd.write(“get %s http/1.0\r\n\r\n” % filename)
fd.flush()
s.shutdown(1)
except socket.gaierror, e:
print “address-related error connecting to server: %s” % e
sys.exit(1)
except socket.error, e:
print “connection error: %s” % e
sys.exit(1)
while 1:
try:
buf = fd.read(2048)
except socket.error, e:
print “error receiving data: %s” % e
sys.exit(1)
if not len(buf):
break
sys.stdout.write(buf)

希望本文所述对大家的python程序设计有所帮助。
